The Daphné-class submarine was a class of the diesel-electric powered submarines designed and constructed for the French Navy in 1964. Marketed by the French government for the export market, the Daphné design went on to serve in South Africa while there were subclasses based on the Daphné design that were commissioned in the navies of Pakistan, Portugal, and Spain. The submarines were in operation between 1964 and the late 1990s, their service lives being extended to fill the capability gap until the newer French nuclear submarines became available. Two French submarines were lost and a third was sunk, but was salvaged.
